Unicode codepoints

[Saul Spatz]

Thanks very much.  This is the elegant kind of solution I was looking for.  I had hoped there was a way to do it without even addressing the matter of surrogates, but apparently not.  The reason I don't like this is that it depends on knowing that python internally stores strings in UTF-16.  I expected that there would be some built-in iterator that would return the code points.  (Actually, this all started when I realized that s[k] wouldn't necessarily give me the kth character of the string s.)
